The skin of infants and young children differs significantly from the skin of adults in structure, function and composition. It is generally accepted that the skin structure and function of infants are in a state of continuous growth and perfection for at least one year after birth. The skin of infants is thinner than the horny layer of adult skin, and the horny cells are small, and are more fragile, sensitive and easily stimulated. As the garment fabric clinging to the skin of a human body, the comfort and the health care function are important indexes for measuring the quality of the fabric, and the selection of the proper garment fabric is very important for infants who cannot express the preference of the infants in language.
The ideal fabric for infants needs to have excellent biocompatibility, air permeability, moisture dispersion, heat retention, handfeel softness, infection-preventing antibacterial property, washing resistance, sun resistance and mildew resistance at the same time. In the prior art, the research and development of fabrics mainly focuses on comfort and beauty, but in life, infants inevitably contact with various microorganisms such as bacteria and fungi, the microorganisms can rapidly breed under proper external conditions, diseases can be spread through contact and the like, and the health and normal life of the infants are influenced. Therefore, the anti-infection and antibacterial functions of the fabric for infants are certainly improved.
In order to improve the anti-infection and antibacterial functions of the fabric, the mainstream treatment mode in the market at present is to add an antibacterial agent into a fabric base material; however, the compatibility problem between the antibacterial agent and the base material leads to poor performance stability, and the antibacterial agent in the prior art is often single in function, poor in broad-spectrum property and limited in antibacterial effect. In addition, the infection-preventing antibacterial fabric for infants on the market has the defects of poor moisture absorption and sweat releasing effects, and further improved waterproofness, flame retardance, ultraviolet aging resistance and wrinkle resistance.
Chinese patent document CN103255538A discloses an anti-ultraviolet and anti-bacterial fabric and a preparation process thereof, the prior art comprises, by weight, 10-15% of viscose negative ion functional fibers, 10-15% of soybean protein fibers, 20-30% of hemp fibers, 5-10% of wool fibers, 5-10% of nano bamboo charcoal fibers, 10-15% of chitin fibers, 2-5% of nano silver ion fibers, 4-6% of an anti-ultraviolet finishing agent and 2-4% of a mosquito repellent agent, and the fabric in the prior art has the effects of ultraviolet resistance, air permeability improvement and bacteriostasis and mosquito repelling. However, the moisture-permeable and sweat-permeable fabric is not ideal in moisture permeability, durability and wrinkle resistance.
Therefore, a more effective method is needed, and the prepared anti-infection and anti-bacterial fabric for infants has the advantages of remarkable anti-infection and anti-bacterial effect, good antibacterial broad spectrum, good comprehensive performance, and excellent moisture absorption and sweat releasing performance, water resistance, flame retardance, ultraviolet aging resistance and wrinkle resistance, and has very important significance.
